Safety Instructions
English
The power supply in this product contains no user-serviceable parts.
Refer servicing only to qualified personnel.
Do not attempt to modify or use the supplied AC power cord if it is
not the exact type required. A product with more than one power
supply will have a separate AC power cord for each supply.
The power button on the system does not turn off system AC power.
To remove AC power from the system, you must unplug each AC
power cord from the wall outlet or power supply.
The power cord(s) is considered the disconnect device to the main
(AC) power. The socket outlet that the system plugs into shall be
installed near the equipment and shall be easily accessible.
SAFETY STEPS: Whenever you remove the chassis covers to
access the inside of the system, follow these steps:
1. Turn off all peripheral devices connected to the system.
2. Turn off the system by pressing the power button.
3. Unplug all AC power cords from the system or from wall
outlets.
4. Label and disconnect all cables connected to I/O connectors
or ports on the back of the system.
5. Provide some electrostatic discharge (ESD) protection by
wearing an antistatic wrist strap attached to chassis ground of
the system-any unpainted metal surface-when handling
components.
6. Do not operate the system with the chassis covers removed.
